Thick Walled Cylinders
On the Constraint-Based Failure Assessment of Thick-Walled Cylinders with Internal Axial Cracks
... The loss of crack tip constraint in a cracked structure leads to enhanced resistance to both cleavage and ductile tearing. However, conventional failure assessment schemes (CEGB-R6, BS-7910) use lower bound toughness ...
